Objective: To provide a quantitative assessment of the literature examining the cross-sectional association between loneliness and depressive symptoms in children and adolescents. Method: A total of 44 studies from 35 articles (n = 27, 214; mean age 13.63 years; 51% female) met inclusion criteria. Results: A medium, positive correlation between loneliness and depressive symptoms in children and adolescents was found (r = .48). Age and gender did not moderate the relationship between loneliness and depressive symptoms. Conclusion: Loneliness may be a particular risk factor for depression. These results have implications for COVID-19 disease containment measures.

The move to online learning during COVID-19 deprived first-year students of friendships and other sources of social support that could buffer against stress during their transition to university. These effects may have been worse for international students than domestic students as many were subjected to travel restrictions or quarantine in addition to the usual stressors. This study examined the impact of COVID-19 on social connectedness and mental health of first-year students enrolled in a metropolitan university in Australia. The study involved 1239 students (30.4% international) and used a 3 (cohorts: 2019, 2020, 2021) × 2 (enrolment status: domestic and international) between-group design. Results showed that both loneliness and university belonging were significantly worse during the first year of COVID-19 compared to the year before or after. Contrary to expectation, domestic students were lonelier than international students across all cohorts. Multiple-group memberships did not change. As predicted, loneliness was moderately to highly correlated with the number of stressors, psychological distress, and (lower) well-being, whereas university belonging and multiple-group memberships were related to positive mental health outcomes. These findings highlight the need for initiatives that promote student connectedness and mental health as the university sector recovers from COVID-19.

Loneliness is an increasingly ubiquitous topic in academic, policy, and healthcare domains. This work typically focuses on its negative physical and mental health consequences, generally employing a singular cognitive definition of loneliness. In doing so, one central aspect of our social world has been neglected in loneliness research and policy: touch. Touch is a fundamental human behaviour and a powerful form of communication which plays a role in physical and psychological wellbeing. This narrative review outlines a conceptual basis upon which to consider the relationship between loneliness and social touch and reviews the available research examining this connection. There are strong indications that these social phenomena can interact in a variety of ways and this review argues that elements of presence, absence, and type of touch may impact upon loneliness experiences. Additionally, this review considers the challenges inherent to researching touch and loneliness, reflecting on their sensitive and subjective nature. The increasing relevance of the touch–loneliness connection is described in light of the COVID-19 pandemic and recommendations are given for research, policy, and practice. This review proposes that touch should be a key topic for investigation in loneliness research and outlines the potentially invaluable role of touch in understanding loneliness.

Loneliness and isolation worsen health and wellbeing have been exacerbated by COVID-19, and represent a significant concern for supporting older adults. Music listening has effects that could be particularly supportive during periods of isolation. The aim of this study is to examine older adults’ music listening behaviour during the COVID-19 pandemic and explore music's social and emotional impact in this context. Semi-structured interviews enhanced with music-elicitation were carried out remotely between May and June 2021. Participants were self-selected, community-dwelling older adults residing in Northern Ireland (N = 14; 6 males; 60–83 years). Most were living with their spouse or family, all were of White ethnicity and had varying levels of education. Data were analysed using reflexive thematic analysis. Two main themes were identified: (1) Music as an emotional resource and (2) Music as a social surrogate. Older adults had a preference for using music to induce positive feelings, and used music for negative affect regulation and consolation. Music acted as a social surrogate providing company, and reminders of social relationships and experiences. Music listening was a valued behaviour during COVID-19. Findings have implications for how music listening might be used as an accessible, low-resource tool for supporting isolated older adults.

Loneliness, a negative emotion stemming from the perception of unmet social needs, is a major public health concern. Current interventions often target social domains but produce small effects and are not as effective as established emotion regulation (ER)-based interventions for general psychological distress (i.e., depression/anxiety). Given that loneliness and distress are types of negative affect, we aimed to compare them within an ER framework by examining the amount of variance ER strategies accounted for in loneliness versus distress, and comparing the ER strategy profiles characterising them. Participants (N = 582, Mage = 22.31, 77.66% female) completed self-report measures of loneliness, distress, and use of 12 cognitive (e.g., cognitive reappraisal) or behavioural (e.g., expressive suppression) ER strategies. Regression analyses revealed that ER explained comparable variance in these constructs. Latent profile analysis identified seven profiles differing in ER patterns, with no distinct loneliness or distress profile identified. Rather, similar patterns of ER characterised these two constructs, involving the greater use of generally maladaptive strategies and the lesser use of generally adaptive strategies. However, loneliness was additionally characterised by less use of strategies involving social connection/expression. Overall, our study supports the utility of ER for understanding loneliness. Established ER-based frameworks/interventions for distress may have transdiagnostic utility in targeting loneliness.

Research has demonstrated that life transitions lead to heightened experiences of loneliness, in part because they engender isolation. We tested whether the degree of isolation during a transition influences loneliness, and if this is due to their effects on social identity processes. Employing an experimental paradigm, Study 1 (N = 213) found that when the transition involved isolation from new networks, in this case studying at university online as opposed to in person, it led to more loneliness, and this was mediated through reduced social identification and continuity of group memberships. Study 2 (N = 215) replicated these effects using a different experimental paradigm in which the transition involved isolation from old group memberships, namely moving to a new neighbourhood from interstate. Study 3 (N = 2346) employed a quasi-experimental repeated-measures design to assess the impact of a highly isolating life transition on loneliness–COVID lockdown. Australians in prolonged lockdown experienced increases in loneliness and this was mediated through (lack of) continuity of group memberships. Overall, these results suggest that isolation needs to be considered when assessing the impact of life transitions on loneliness. Moreover, the mediation results indicate that isolating transitions may be responsible for loneliness because these make it difficult to maintain crucial group memberships and form a sense of identification with relevant new groups.
